Well, the ONLY game to ever have true newtonian physics without the fantasy weapons was one of the first CD-ROM games, MANTIS: EXPERIMENTAL FIGHTER. You can download the whole game from
http://www.theunderdogs.org/game.php?id=2107 . Note: its OLD so graphics are barely 256 colors in-game. The storyline and cinematics are very cool though.
In space there can be fighters. In fact, I believe that fighters would be even far more useful in space. A small craft armed with missiles.. even nuke-tipped missiles, will be able to beat the crap out of a massive cap ship if it scores a hit. And since shields are for the trekkies, big ships mean they wont be able to dodge a homing missile, countermeasures mostly useless (jam a video or laser guided missile? yah right)... a small squad of fighters would spell death to a flotilla of large vessels.
1)G-Forces: The only game to have ever tried to have G-forces and newtonian stuff was TERMINUS. And it was never finished. A real shame, the game showed promise.
4+5.) Mantis has this modeled. Running outta gas was not nice.
6) Mantis takes place mostly in the solar system, with the few incursions you make into other solar systems as part of the missions you must fly.
8+9) Mantis has what you say. The Mantis weapons are a machine gun (a rail gun) with limited ammo, the Mantis has 2 point defense automated turrets on the wings to shoot down incoming missiles (and they also have limited ammo), and missiles ranging from nuclear missiles to standard warhead missiles, cameras for recon and a laser system which you have to wait for it to recharge before every shot.
imo, space weapons would most likely be either projectile (missiles and bullets) for most crafts, beam weapons like lasers and masers would most likely be mounted on larger vessels that would be able to power them and put them on turrets of sorts. Nuclear missiles would not be the norm, you just cant give control of such powerful things to the armed forces in general. Besides, a conventional warhead in a missile would be devastating anyway. Missile hits ship,penetrates (like those anti-bunker missiles) explodes, shockwave tears the innards of the ship apart (as missile warhead interacts with ship's atmosphere). Not to mention the kinetic impact in the first place.

The review: "Mantis is one of the least known Microplay / Microprose games ever made, and for good reason: it is a mediocre ship-to-ship flight combat simulator that offers nothing new to fans of the genre. As M. Evan Brooks observes in his mini-review: "[the game] accomplished its mission adequately, but without dash or superlatives. The CD version was much more challenging, although even here, the challenge seemed to be more of the same." The graphics and sound are adequate, but most missions (even the extra ones in CD version) are of the boring kill-everything-in-sight variety. Overall, a very disappointing release from Microplay, maker of such underdogs as Midwinter series and Sea Rogue. Fans of space combat games should definitely play / replay numerous better games, such as the Wing Commander series.
Note: This download is the floppy version, with speech add-on included."
Is on the money on only 2 things: Its shoot-em-all in sight missions which are the only kind of mission you get throught 95% of the game and its long.
What this guy didnt mention is that its the only game so far (and this review was done waaaay back then) to use realistic newtonian flight, a VERY intuitive radar system (much, much better than Wing Commander's.. the one in MANTIS is almost 3-D! Back in those days! wow!) and a very helpful autopilot systems. Id say this is a space combat SIM, not a space combat GAME.
You could also try out Independence War (I-War) , its good graphics and newtonian flight model are excellent, albeit the game royally SUCKS. If it wasnt for the incredible flight model, it'd a waste of hard disk space.
Finally, while not a real-flight physics game, check out BATTLECRUISER MILLENIUM. (
